image/jpeg: panic while decoding a JPEG image #4259
Description
by samuel.stauffer:
With the latest tip version of go (as of yesterday), I get a panic when decoding the
attached JPEG image. The image is grayscale and quite possibly corrupt.
When i try with go 1.0.3 I get an error returned with no panic. The error is:
"invalid JPEG format: missing 0xff00 sequence"
The panic:
panic: runtime error: index out of range
goroutine 1 [running]:
